DETAILED DESCRIPTION

Various aspects of the present disclosure relate generally to infant pacifier with interchangeable nipples.

INTRODUCTION

According to some embodiments, an infant pacifier includes a shield, a nipple member, and a cap. The shield includes opposite front and rear surfaces. An opening is substantially centered within the shield, and an annular sleeve extends from the rear surface.

The annular sleeve is circumferentially aligned with a perimeter of the opening and includes an inner surface, an outer surface, and a distal free end. A notch is formed within the annular sleeve inner surface.

The nipple member includes an annular base with opposite first and second ends. A nipple extends outwardly from the first end of the annular base, and a flange is located at the opposite second end of the base. The nipple member is inserted through the shield opening such that the nipple extends outward from the shield front surface. The annular base includes an outwardly extending rib that mates with the notch in the annular sleeve inner surface to limit relative rotation of the nipple member and shield during use. The flange abuts the distal free end of the shield annular sleeve when the pacifier is assembled.

The cap is configured to maintain engagement of the nipple member and shield and is removably secured to the shield annular sleeve. In some embodiments, the outer surface of the sleeve includes outwardly protruding locking members that engage an underside of the cap when the cap and sleeve are twisted relative to each other.

In some embodiments, the nipple member is formed from an elastomeric material, such as silicon, and has a constant thickness throughout.

In some embodiments, the nipple has a smooth outer surface.

In some embodiments, the nipple has a mesh-like structure with holes. In some embodiments, the nipple has a textured outer surface.

In some embodiments, the cap and the shield are formed from a paper-based composite material, such as Richlite®.

For example, in FIG. 1, an infant pacifier 10, according to some embodiments of the present disclosure, includes a shield 20, a nipple member 40, and a cap 60. The shield 20 has a generally planar shape with opposite front and rear surfaces 22, 24.

Although, in some embodiments, the shield 20 may have an arcuate shape. An opening 26 is formed within the shield 20 and is substantially centered within the shield 20. The opening 26 is configured to receive the nipple member 40 therethrough. The illustrated shield 20 includes a ventilation aperture 28 on each side of the opening 26 (e.g., passing between the front and rear surfaces 22, 24). An annular sleeve 30 extends from the shield rear surface 24 and is circumferentially aligned with a perimeter of the opening 26, as illustrated. The annular sleeve 30 has an inner surface 32, an outer surface 34, and a distal free end 36.

A notch 38 is formed within the inner surface 32 of the shield as illustrated and is configured to engage (e.g., mate) with a rib in the nipple member 40. See, e.g., FIGS. 3A-3B for great detail of the notch 38. The inner surface 32 of the annular sleeve 30 has a tapered portion 32t adjacent the distal free end 36 as illustrated in FIG. 3B. The notch 38 begins at the distal free end 36 and extends through the tapered portion 32, as illustrated. The notch 38 has a generally rectangular configuration that is configured to matingly receive a correspondingly shaped rib 48 on the nipple member 40. However, the notch 38 and the rib 48 may have various shapes and configuration, and embodiments of the present disclosure are not limited to the illustrated shape and configuration of the notch 38 and the rib 48.

The illustrated nipple member 40 has an annular base 42, a nipple 44 extending outwardly from a first end 42a of the annular base 42, and a flange 46 at an opposite second end 42b of the base 42. The nipple member 40 is inserted through the shield opening 26 such that the nipple 44 extends outward from the shield front surface 22. The annular base 42 includes an outwardly extending rib 48 that is configured to mate with the notch 38 in the annular sleeve inner surface 32 to limit relative rotation of the nipple member 40 and shield 20 when the pacifier 10 is assembled. The flange 46 abuts the distal free end 36 of the shield annular sleeve 30 when the pacifier 10 is assembled.

In some embodiments, the nipple member 40 is formed from an elastomeric material, such as silicon, and has a constant thickness throughout. In some embodiments, the nipple 44 may have a mesh-like structure with holes, and the nipple 44 may have a hollow interior that is configured to receive frozen fruit and other such items therein. In some embodiments, the nipple 44 may have a textured outer surface. In some embodiments, the nipple 44 may have a smooth outer surface.

The nipple member 40 may have various shapes and sizes, such as illustrated in FIGS. 8-10. Also, in some embodiments, a set of different size nipples may be provided (e.g., decreasing in size and used for weaning). Because the cap 60 is removably secured to the shield 20, the interchangeability of different nipple members 40 is facilitated.

The cap 60 is configured to maintain the engagement of the nipple member and shield such that the nipple member 40 cannot become dislodged from the shield 20 during use. The cap 60 is removably secured to the shield annular sleeve 30, such as via twist-lock features or threads.

In some embodiments, the cap 60 and the shield 20 may be formed from a paper-based composite material, such as Richlite®.

Further, an infant pacifier 10 according to other embodiments of the present disclosure may include similar or different features. See, e.g., FIGS. 4-11. The illustrated pacifier 10 is similar to the pacifier 10 illustrated in FIGS. 1, 2A-2B and 3A-3B in that the pacifier 10 includes a shield 20, a nipple member 40 and a cap 60. The illustrated shield 20 has a generally planar shape with opposite front and rear surfaces 22, 24. An opening 26 is formed within the shield 20 and is configured to receive the nipple member 40 therethrough. The illustrated shield 20 includes a ventilation aperture 28 on each side of the opening 26. An annular sleeve 30 extends from the shield rear surface 24 and is circumferentially aligned with a perimeter of the opening 26, as illustrated. The annular sleeve 30 has an inner surface 32, an outer surface 34, and a distal free end 36.

The outer surface 34 of the sleeve 30 includes laterally and oppositely extending locking members 70 that are configured to be removably engaged with the underside of the cap 60 when the cap 60 and sleeve 30 are engaged and twisted relative to each other. The illustrated locking members 70 have an arcuate shape, as illustrated. The locking members 70 are configured to be received within respective channels 80 formed within the cap 60. Each channel 80 has a tapered configuration such that, upon twisting the cap 60 and shield 20 relative to each other, each locking member 70 is compressed which provides a releasable yet secure connection between the cap 60 and the shield 20.

The nipple member 40 illustrated in FIG. 7 includes an annular base 42, a nipple 44 extending outwardly from a first end 42a of the annular base 42, and a flange 46 at an opposite second end 42b of the base 42. The nipple member 40 is inserted through the shield opening 26 such that the nipple 44 extends outward from the shield front surface 22. The annular base 42 includes a pair of outwardly extending, opposing ribs 48 that are configured to mate with respective notches 38 in the annular sleeve inner surface 32 to limit relative rotation of the nipple member 40 and shield 20 when the pacifier 10 is assembled.

The notches 38 are formed by the arcuate locking members 70. The flange 46 abuts the distal free end 36 of the shield annular sleeve 30 when the pacifier 10 is assembled.

In some cases, the pacifier may include a handle portion (not depicted, e.g., connected or is a part of the shield portion or cap portion). The nipple portion may be configured for insertion into an infant's mouth. The shield portion may be connected to the nipple portion and may be designed to remain outside the infant's mouth during use. The cap portion may engage the shield portion to retain the nipple portion in place. The handle portion may extend from the shield portion and may provide a gripping area for a caregiver or the infant.

The pacifier may, in some aspects, include a nipple portion fabricated from a soft, flexible material suitable for infant oral contact. The shield portion may be constructed from a rigid or semi-rigid material and may feature a curved or contoured shape designed to comfortably fit against an infant's face. In certain implementations, the handle portion may be integrated with the shield portion or may be separately attached.

Referring to FIG. 1, a pacifier 10 may comprise several main components, including a shield 20, a nipple member 40, and a cap 60. In some aspects, the shield 20 may include opposite front and rear surfaces 22, 24. The shield 20 may comprise an opening 26 that, in some cases, is substantially centered within the shield 20. An annular sleeve 30 may extend from the rear surface 24 of the shield 20. In certain implementations, the annular sleeve 30 may be circumferentially aligned with a perimeter of the opening 26.

The shield 20 may, in some cases, include one or more ventilation apertures 28. These ventilation apertures 28 may allow for air circulation and may help prevent moisture buildup during use of the pacifier 10.

In some aspects, the nipple member 40 may be inserted through the opening 26 of the shield 20. When assembled, the nipple 44 of the nipple member 40 may extend outward from the front surface 22 of the shield 20. This configuration may allow an infant to easily access and suckle on the nipple 44 while the shield 20 remains outside the infant's mouth.

The annular sleeve 30 may comprise an inner surface 32, an outer surface 34, and a distal free end 36. In some implementations, the inner surface 32 of the annular sleeve 30 may include at least one notch 38. This notch 38 may be designed to interact with corresponding features on the nipple member 40.

The nipple member 40 may consist of a base 42, the nipple 44 extending outwardly from the base 42, and a flange 46 at the opposite end of the base 42. In some cases, the base 42 may include at least one outwardly extending rib 48. This rib 48 may be configured to mate with a corresponding notch 38 in the annular sleeve 30 of the shield 20.

The cap 60 may be designed to be removably secured to the annular sleeve 30 of the shield 20. In some implementations, this configuration may allow the cap 60 to retain the nipple member 40 in place and maintain its orientation relative to the shield 20.

Referring to FIG. 2A, a nipple member 40 for a pacifier may comprise several components, including a base 42, a nipple 44, a flange 46, and a rib 48. In some aspects, the base 42 may be an annular structure with a first end 42a and a second end 42b. The nipple 44 may extend outwardly from the first end 42a of the base 42. In certain implementations, the flange 46 may be positioned at the opposite second end 42b of the base 42.

The nipple 44 may have an elongated shape that extends from the base 42, providing a suckling surface for an infant. In some cases, the nipple 44 may comprise an elastomeric material. The elastomeric material may include, but is not limited to, silicone, natural rubber, or synthetic rubber. In certain aspects, the nipple 44 may have a constant (or varied) thickness throughout its structure. The constant (or varied) thickness may contribute to uniform (or not) flexibility and durability of the nipple 44.

The flange 46 at the second end 42b may have a wider diameter than the base 42. In some implementations, this wider diameter may assist in securing the nipple member 40 to other components of the pacifier. For example, the flange 46 may be compressed between a cap and a sleeve of the pacifier assembly.

In some aspects, the rib 48 may protrude outwardly from the outer surface of the base 42. The rib 48 may be positioned between the first end 42a and the second end 42b of the base 42. In certain cases, the rib 48 may abut or be spaced apart from the flange 46. The rib 48 may be designed to mate with a corresponding notch in the pacifier's shield assembly. This mating configuration may serve to limit rotation of the nipple member 40 relative to the shield, ensuring proper orientation of the nipple 44 during use.

In some implementations, the nipple member 40 may include multiple ribs 48. For example, a pair of outwardly extending, opposing ribs may be configured to mate with respective notches in an annular sleeve of the pacifier shield. This configuration may provide enhanced stability and rotational control of the nipple member 40 within the pacifier assembly.

The design of the nipple member 40 may allow for easy assembly and disassembly of the pacifier. In some cases, this design may facilitate cleaning and maintenance of the pacifier. Additionally, the configuration of the nipple member 40 may allow for interchangeability, enabling the use of nipple members with different nipple shapes or sizes within the same pacifier assembly.

Referring to FIG. 2B, a detailed view of a portion of the nipple member 40 is shown, labeled as “DETAIL A”. The figure illustrates a cross-sectional view of the base 42 of the nipple member 40. In some aspects, the base 42 may have a curved profile and may comprise several distinct features.

At one end of the base 42, the flange 46 may extend outward from the base 42. In some implementations, the flange 46 may extend axially from the base 42 in a flat disk-like shape. The flange 46 may have a curved shape, following the contour of the base 42. This curved shape may allow the flange 46 to conform to the shape of other components in the pacifier assembly.

Protruding from the outer surface of the base 42 may be a rib 48. In some aspects, the rib 48 may be depicted as a rectangular protrusion extending outward from the base surface. The rib 48 may serve as a mechanism for securing or aligning the base 42 within the pacifier assembly. In certain implementations, the base 42 may include one or more ribs 48.

The base 42 may be divided into two sections: a first end of the annular base 42a and a second end of the annular base 42b. In some cases, the first end 42a may be located at the top of the base 42, while the second end 42b may be indicated at the bottom. This division may contribute to the functionality of the nipple member 40 within the pacifier assembly.

The overall shape of the base 42 may be a curved, cylindrical structure designed to fit within a larger assembly. In some aspects, the various elements—the flange 46, rib 48, and the differentiated ends of the base 42a, 42b—may be integral parts of the base's design, contributing to its functionality within the complete pacifier structure.

In certain implementations, the rib 48 may be configured to mate with a corresponding notch in an annular sleeve of a pacifier shield. This mating configuration may serve to limit relative rotation of the nipple member 40 and the shield. By engaging the rib 48 with a notch, the nipple member 40 may be held in a specific orientation relative to the shield, which may help maintain proper positioning of the nipple during use.

The design of the base 42 with its various features may allow for secure attachment of the nipple member 40 to other components of the pacifier while also facilitating easy assembly and disassembly. This configuration may enable interchangeability of nipple members, allowing for the use of different nipple shapes or sizes within the same pacifier assembly.

Referring to FIG. 3A, a portion of a pacifier is illustrated, focusing on the shield 20 and annular sleeve 30 components. In some aspects, the shield 20 may be partially shown, with the annular sleeve 30 extending from it. The annular sleeve 30 may comprise an inner surface 32 and an outer surface 34. In certain implementations, the inner surface 32 may include at least one notch 38. This notch 38 may have a matching profile to the rib 48 of the nipple member, for example, a rectangular recess within the sleeve.

The annular sleeve 30 may terminate at a distal free end 36. In some cases, adjacent to the distal free end 36, the inner surface 32 may feature a tapered portion 32t. This tapered portion 32t may gradually expand the inner diameter of the sleeve towards the distal free end 36 (and narrow the inner diameter sleeve towards the front surface). The tapered portion 32t may facilitate insertion of the nipple member or provide a more secure fit when assembled.

The figure may also show the curvature of the shield 20, indicating its three-dimensional shape. In some implementations, the annular sleeve 30 may extend perpendicularly from the shield 20, creating a cylindrical protrusion. This configuration may allow for proper alignment and secure attachment of the nipple member and cap.

The structural design of the annular sleeve 30 and its features may provide mating functionality of this portion of the pacifier. In particular, the notch 38 and tapered portion 32t may ensure the assembly and functionality of the complete pacifier device. For example, the notch 38 may interact with corresponding features on the nipple member to limit rotation, while the tapered portion 32t may assist in guiding components during assembly or provide a compression fit.

In some aspects, the annular sleeve 30 may be circumferentially aligned with a perimeter of an opening in the shield 20. This alignment may ensure proper positioning of the nipple member when inserted through the opening. The configuration of the annular sleeve 30, including its surfaces, notch, and tapered portion, may contribute to the overall stability and functionality of the pacifier assembly.

Referring to FIG. 3B, a detailed sectional view of a portion of the annular sleeve 30 is illustrated, labeled as “DETAIL B”. In some aspects, the annular sleeve 30 may comprise an inner surface 32 and an outer surface 34. The inner surface 32 may form a concave curve, while the outer surface 34 may form the convex side of the curved structure, mirroring the shape of the inner surface 32 but with a smooth, uninterrupted profile.

In certain implementations, a notch 38 may be formed within the inner surface 32 of the annular sleeve 30. The notch 38 may be represented by an indentation in the inner surface 32. In some cases, the notch 38 may have a rectangular configuration. This rectangular configuration may correspond to the shape of a rib on the nipple member, allowing for a secure mating between the components.

The annular sleeve 30 may terminate at a distal free end 36. In some aspects, the distal free end 36 may be open, continuously with the opening 26, allowing for insertion of the nipple member into the opening and engagement with the notch 38.

Adjacent to the distal free end 36, the inner surface 32 may feature a tapered portion 32t. In certain implementations, this tapered portion 32t may gradually widen the inner diameter of the structure as it approaches the distal free end 36. The tapered portion 32t may serve various functions, such as guiding the insertion of the nipple member, facilitating assembly, or providing a more secure fit when the pacifier is assembled.

The combination of these features—the inner surface 32, outer surface 34, distal free end 36, notch 38, and tapered portion 32t—may form a part of the pacifier's design, contributing to its assembly and functionality. For example, the notch 38 may interact with a corresponding rib on the nipple member to limit relative rotation between the components. The tapered portion 32t may assist in aligning and securing the nipple member within the annular sleeve 30.

In some cases, the annular sleeve 30 may include multiple notches 38 formed within the inner surface 32. These notches 38 may be positioned at various locations around the circumference of the inner surface 32, corresponding to multiple ribs on the nipple member. This configuration may provide enhanced stability and rotational control of the nipple member within the pacifier assembly.

The design of the annular sleeve 30, with its specific features such as the notch 38 and tapered portion 32t, may allow for secure attachment of the nipple member while also facilitating easy assembly and disassembly of the pacifier. This configuration may enable interchangeability of nipple members, allowing for the use of different nipple shapes or sizes within the same pacifier assembly.

Referring to FIG. 4, an exploded view of a pacifier 10 is illustrated. In some aspects, the pacifier 10 may comprise several components, including a shield 20, an annular sleeve 30, a flange 46, and a cap 60.

The shield 20 may form the main body of the pacifier 10 and may include a front surface 22 and a rear surface 24. The shield 20 may comprise one or more ventilation apertures 28, which may allow for air circulation.

Extending from the shield 20 may be the annular sleeve 30, which may have an outer surface 34. In some cases, the annular sleeve 30 may be designed to accommodate other components of the pacifier 10. The flange 46 may be positioned above and abutting the distal free end of the annular sleeve 30. This configuration may help secure the nipple member within the pacifier assembly.

The cap 60 is shown separated from the other components, positioned above the shield 20. In some implementations, the cap 60 may be designed to fit over the annular sleeve 30 and may be configured to maintain engagement of the nipple member and shield. The cap 60 may be removably secured to the shield annular sleeve 30, allowing for disassembly and reassembly of the pacifier 10 as needed.

In certain aspects, locking members 70 may be visible on the outer surface 34 of the annular sleeve 30. These locking members 70 may be designed to engage with the cap 60 when the pacifier 10 is assembled. In some cases, the locking members 70 may comprise outwardly protruding structures that engage an underside of the cap 60 when the cap 60 and sleeve 30 are twisted relative to each other. This configuration may provide a secure attachment mechanism while still allowing for removal of the cap 60 when necessary.

The exploded view may demonstrate how these components are arranged and how they may fit together to form the complete pacifier 10. This design may allow for easy assembly and disassembly, which can facilitate cleaning and maintenance of the pacifier 10. In some implementations, this configuration may also allow for interchangeable nipple members, with different nipple shapes or sizes.

Referring to FIG. 5, a perspective view of a cap 60 component of a pacifier is illustrated. In some aspects, the cap 60 may be shown as a circular disc-like component designed to fit over the annular sleeve 30 of the pacifier shield. The cap 60 may be configured to maintain engagement of the nipple member and shield when assembled.

In certain implementations, the cap 60 may be secured to the shield annular sleeve 30 via a twist-lock mechanism. This mechanism may allow for easy attachment and removal of the cap 60 while providing a secure connection during use.

Inside the cap 60, tapered channels 80 may be visible. These tapered channels 80 may be grooves or indentations within the inner surface of the cap 60. In some cases, the tapered channels 80 may be arranged in a circular pattern, corresponding to the circular shape of the cap 60.

The tapered channels 80 may be configured to receive locking members located on the outer surface of the annular sleeve 30. The tapered configuration of the channels 80 may facilitate engagement with the locking members and may contribute to the security of the twist-lock mechanism. As the cap 60 is twisted onto the annular sleeve 30, the locking members may slide along the tapered channels 80, gradually tightening the connection between the cap 60 and the annular sleeve 30.

In some aspects, the tapered configuration of the channels 80 may allow for a range of engagement positions, accommodating slight variations in manufacturing tolerances or wear over time. This design may help ensure a consistently secure fit between the cap 60 and the annular sleeve 30.

The cap 60 and its internal features, such as the tapered channels 80, may be manufactured from various materials. In some implementations, the cap 60 may comprise a paper-based composite material, which may provide durability while offering environmental benefits.

Referring to FIG. 6, a rear view of a pacifier component is illustrated. In some aspects, the rear surface 24 of a shield 20 may be shown. The shield 20 may have an overall curved shape (e.g., butterfly-like or other design). In certain implementations, the shield 20 may have an arcuate shape, which may allow it to comfortably conform to an infant's face during use.

At the center of the shield 20, an opening 26 may be present. In some cases, this opening 26 may be surrounded by an annular sleeve 30 that extends from the rear surface 24 of the shield 20. The annular sleeve 30 may be circumferentially aligned with the perimeter of the opening 26.

Within the inner circumference of the annular sleeve 30, the annular sleeve 30 includes two notches 38. These notches 38 may be positioned opposite each other and may be designed to interact with corresponding ribs on a nipple member. In certain aspects, the notches 38 may serve to limit rotation of the nipple member relative to the shield 20.

The shield 20 may also include two locking members 70. In some cases, these locking members 70 may be circular protrusions located on either side of the central opening 26. The locking members 70 may be positioned on the outer surface of the annular sleeve 30 and may be designed to engage with a cap to secure the assembly. In certain implementations, the locking members 70 may have an arcuate shape, which may facilitate smooth engagement with corresponding features on the cap.

In some aspects, the shield 20 may include one or more ventilation apertures. These ventilation apertures may allow for air circulation and may help prevent moisture buildup during use of the pacifier.

The overall design of the shield 20 and its components may allow for the secure attachment of a nipple and a cap, while also providing a comfortable shape for the user (e.g., infant). The arcuate shape of the shield 20, combined with the positioning of the locking members 70 and the configuration of the notches 38, may contribute to the functionality and ease of assembly of the pacifier.

Referring to FIG. 7, a perspective view of a nipple member 40 for a pacifier is illustrated. In some aspects, the nipple member 40 may comprise a base 42 and an elongated nipple portion extending from the base 42. The base 42 may include a first end 42a, which may be connected to the nipple portion, and an opposite second end 42b. At the second end 42b, a flange 46 may extend outwardly from the base 42. In certain implementations, the flange 46 may have a circular shape and a larger diameter than the base 42.

The base 42 may feature outwardly extending ribs 48 positioned on opposite sides. In some cases, the nipple member 40 may comprise a pair of outwardly extending, opposing ribs 48 configured to mate with respective notches in the annular sleeve inner surface of the pacifier's shield component. This configuration may provide enhanced stability and rotational control of the nipple member 40 within the pacifier assembly.

The nipple portion of the nipple member 40 may have a generally elongated, tapered shape that extends from the first end 42a of the base 42. In some implementations, the nipple portion may have a smooth outer surface. This smooth surface may provide a comfortable suckling experience for an infant and may facilitate easy cleaning of the nipple member 40.

The design of the nipple member 40 may allow for secure attachment to other components of the pacifier while providing a suitable shape for an infant to suckle on. The ribs 48 and flange 46 may contribute to the proper positioning and retention of the nipple member 40 within the pacifier assembly.
